摘要
研究混凝土桥梁耐久性具有重要意义。本文分析了由于混凝土的裂缝、钢筋锈蚀、冻融破坏、碱—集料反应及混凝土表层渗透性等对桥梁混凝土耐久性的影响问题,并提出了如何提高桥梁混凝土结构耐久性的几点建议。
The problem of structure durability of concrete bridge hasn't been received enough attention in China's engineering field. The effects of concrete cracks, steel bar corrosion, freezing and thawing failures, alkali-aggregate reaction and permeability of concrete surface on durability of concrete bridge were analyzed and some measures of improving the structure durability of concrete bridge were presented in the paper.
